The PPM Formaldemeter htv is an easy-to-use, hand held three parameter indoor air quality monitor, designed for the rapid measurement of airborne formaldehyde levels, along with temperature and humidity readings.
The PPM Formaldemeter htv is designed, using built in data analysis functions, to compensate for high humidity readings, which can act as interference to the instrument's readings.
